The **17AC-AA6-R** is a specific model of a **Miniature Basic Switch** (often referred to as a microswitch) manufactured by **Honeywell** as part of their **AC Series**. These switches are primarily used for door interlock applications and manual power cut-off safety mechanisms. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the 17AC-AA6-R: | Feature | Specification | | :--- | :--- | | **Type** | Door Interlock Switch | | **Actuator Type** | Rod / Pull-to-Cheat (Plunger) | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | 15 Amps | | **Voltage Rating** | 125 VAC / 250 VAC | | **Termination Style** | Screw Terminals | | **Mounting** | Panel Mount / Bracket | | **Housing Material** | Stainless Steel / Die-cast Zinc | --- ### 2. Physical Components & Design The "electronic" part of this device is electromechanical. It consists of several critical internal components: * **Plunger Mechanism:** A spring-loaded rod that detects the presence or absence of a door or panel. * **Snap-Action Contact:** A precision internal mechanism that ensures rapid switching of electrical contacts regardless of the speed at which the plunger is moved. * **"Pull-to-Cheat" Feature:** This is a safety override. In maintenance mode, a technician can pull the plunger out to keep the circuit closed (energized) even while the door is open, allowing for testing. * **Screw Terminals:** Heavy-duty connection points designed for secure wiring in industrial environments. --- ### 3. Functional Operation The 17AC-AA6-R operates on a simple logic transition: 1. **Door Closed:** The plunger is depressed, completing the circuit and allowing the machine to run. 2. **Door Opened:** The plunger is released, snapping the internal contacts to the "Open" position, instantly cutting power to the machinery. 3. **Maintenance Mode:** The plunger is manually pulled outward, bypassing the safety cut-off for diagnostic purposes. --- ### 4. Common Applications Due to its rugged design and high amperage rating, it is commonly found in: * **Vending Machines:** To cut power when the front panel is opened. * **Appliances:** Microwave doors or industrial ovens. * **Control Cabinets:** Ensuring power is disconnected when an electrical bay is accessed. * **Office Equipment:** High-speed copiers and printers.
